Acid reflux can do more than cause occasional heartburn. For some people, symptoms become particularly troublesome at night, making it difficult to fall asleep or stay asleep. Repeated sleep disruption may affect energy levels, concentration, mood and overall quality of life.
Understanding why acid reflux worsens at night and taking steps to manage it can help improve both digestive health and sleep quality.
Why Is Acid Reflux Worse at Night?
Acid reflux occurs when stomach acid flows back into the oesophagus. During the day, gravity helps keep stomach contents where they belong. However, when you lie down, stomach acid can more easily travel upwards into the oesophagus.
Several factors may contribute to night-time reflux, including:
- Eating large meals close to bedtime
- Consuming trigger foods such as spicy, fatty or acidic foods
- Being overweight or obese
- Pregnancy
- Smoking
- Certain medications
As a result, symptoms such as heartburn, regurgitation, coughing and throat irritation may become more noticeable during the night.
How Can You Sleep Better with Acid Reflux?
Lifestyle modifications can help reduce reflux symptoms and improve sleep quality.
Avoid Eating Close to Bedtime
Eating shortly before lying down increases the likelihood of stomach acid flowing back into the oesophagus. Try to finish your evening meal at least two to three hours before going to bed to allow proper digestion.
Identify and Avoid Trigger Foods
Limit intake of spicy, fried and fatty, acidic (citrus fruits, tomatoes) foods, carbonated drinks, and caffeinated beverages. Triggers vary from person to person, so keeping a food diary may help identify foods that worsen your symptoms.
Elevate Your Head While Sleeping
Raising your upper body while sleeping may help reduce reflux by using gravity to keep stomach contents down. A wedge pillow or an elevated bed head may be more effective than stacking multiple pillows.
Sleep on Your Left Side
Research suggests that sleeping on the left side may help reduce acid reflux symptoms compared to sleeping on the right side or lying flat on the back.
Maintain a Healthy Weight
Excess weight can place additional pressure on the stomach, increasing the risk of acid reflux. Maintaining a healthy weight may help reduce symptom frequency and severity.
Could Night-Time Acid Reflux Be a Sign of GERD?
Occasional acid reflux is common and may not require medical treatment. However, frequent symptoms could indicate gastroesophageal reflux disease (GERD), a chronic condition where acid reflux occurs regularly.
Left untreated, GERD may lead to complications such as inflammation of the oesophagus, narrowing of the oesophagus or changes to the oesophageal lining.
If reflux symptoms occur frequently or disrupt your sleep on a regular basis, it may be time to seek medical advice.
When Should You See a Doctor for Acid Reflux?
You should consult a doctor if you experience:
- Acid reflux symptoms more than twice a week
- Difficulty swallowing
- Persistent cough or hoarseness
- Unexplained weight loss
- Chest discomfort
- Symptoms that do not improve despite lifestyle modifications
A gastroenterologist can evaluate your symptoms and recommend appropriate investigations and treatment options.
Frequently Asked Questions About Acid Reflux and Sleep
Can acid reflux cause insomnia?
Yes. Reflux symptoms such as heartburn, coughing and regurgitation can make it difficult to fall asleep and may cause repeated awakenings throughout the night.
What should I drink before bed if I have acid reflux?
Water is generally the safest option. Avoid alcohol, caffeinated beverages and carbonated drinks close to bedtime if they trigger your symptoms.
Does drinking water help acid reflux at night?
Drinking water may temporarily help clear acid from the oesophagus for some individuals, but it is not a treatment for persistent reflux symptoms.
